The Visual FoxPro 9 Report System includes a number of new features designed for extensibility, including a new ReportListener base class. The ReportListener-based classes in this class library are identical to the classes built into the Report Output Application. ReportListener Base Foundation Class. The UpdateListener class provides user feedback during report runs. XmlDisplayListener tunes XmlListener's XML settings suitably for presentation output needs, and adds image-file-publishing functionality.

Promoting, selling, recruiting, coursework and thesis posting is forbidden. Students Click Here. I am trying to use the HTML report listener within one of my forms. It works great except it keeps displaying listener messages. Any idea how to get rid of those? No such luck. VCX End of Locate scope. I have searched the internet and VFP help files and can't find anything on this topic.
Anybody know how to suppress these messages? Thanks for the help. But referring to the help this has no influence in the object assisted mode, if the reportlistener does not repect this setting given via command clauses. Report listener source code is in xsource available to you to modify otherwise.
I already have the Set console off option and as you stated it doesn't have an effect on the listener. I just tried the set form. While it doesn't get rid of the messages, it does move them off my form and into the background. It isn't perfect, but it is better. I am not big on modifying foxpro source code. This is really such a basic thing, I would think VFP would have an easy solution.
Like some setting. I just can't find it. Thanks for the suggestion, but I have status set to off. Doesn't seem to impact the listener. Wasn't this a bug that was reported in one of the VFP releases, guys? Then you can setAllowOutput. If you don't use subclassing, start right now, this is very often a best solution to have one central base class all other classes inherit of, to set something in all objects derived.
Even if you don't make any other use of OOP, this is the one thing you can always do, class browser anables you to redefine your classes and also scx forms to be based on other classes than the native ones.
Bye, Olaf. Clmcgrath, What exactly are the messages you are seeing? Are you referring to the actual report output, or are these some sort of error messages? If the latter, it could be similar to a problem I had last year. See thread Spurious error messages when using report listener to preview a report for details. I never found the cause of the problem, but I solved it satisfactorily by modifying the report listener code.
Quote: What exactly are the messages you are seeing? Quote: Presumably the ones included in the original post. Thanks to everyone for their help.
I think that put the messages somewhere in the background that can no longer be seen. It worked! THe article above probably works also.
It's just a bit more techy. Simply move This. Clmcgrath, It's good that you have made the problem go away, but I really think you should adopt Cathy Pountey's solution rather than the one you did.
What you have done is to hide the effects of the problem. With Cathy's suggestion, you would actually solve it. I don't normally like to add to a pileup, but here I will.
You're betting that the next time it comes up, someone here will either remember this thread or Cathy's blog post. At our collective ages, relying on memory isn't the best bet. Fix the problem once and for all. It's seriously easy. There is no This. Below is the code. Unless I'm looking in the wrong place, the blog advice does not appear to be helpful. AddProperty "isSuccessor",. Use Olaf's code and it will open the right class.
Heh, If we're totally going to make it easy, we could use WriteMethod and do the whole deed. Dan, ; Sorry, clmcgrath. We're making a little fun of you. For a programmer it should not be "too technical" to move one line of code before one other line. So I think you was lost in this description to solve the bug in some way.
It still makes me wonder why, though. Supressing output is something I suggested and this is finefor this one case. And this is normally the case in my apps. Others might have other needs. So Dan is right: This is best be fixed at the root. I'll have a look into that and see if there still needs to be a fix in the VFPX version. The fact remaining is, this is a bug of the FFC reportlisteners and should be fixed.
Ok, here is my findings: 1. I first checked, if the unmodified versions of both the SP2 fxlistner and the VFPX fxlistener create any output on the screen. This means I couldn't reproduce your problem. The reportoutput. It's not based on the ffc reportlisteners. So the problem must be somewhere else. Judging from the output it still does not look like a problem in your report, but somewhere within the reportoutput. It's hard to find the problem without a repro of the error, though.

Presumably the ones included in the original post. That's what comes of skimming rather than reading. Clmcgrath, put that command in the Load or Init of the form that calls the report. If that doesn't work, add it to the start of the report listener code. The command is scoped to the data session, so it's not enough to put it in the main program.

Working with reports,olecontrols and listener class
In this section, we are going to cover how the object-assisted reporting engine works during a report run. By default, the reporting system in VFP 9. Of course, that's not the end of the story. The report engine in VFP 9.
During the run of a report, VFP raises events in a report listener as they happen. For example, the LoadReport event of a report listener fires when the report is loaded before being run. When an object is drawn on the report page, the Render method fires. The ReportListener base class has some native behavior, but extensibility really kicks in when you create and use your own subclasses. For example, a subclass of ReportListener could dynamically format a field, so under some conditions it prints with red text and under other conditions it prints in black. This chapter starts with a discussion of how report listeners work, and then moves on to examining the properties, events, and methods PEMs of the ReportListener base class. Report listeners produce output in two ways.
In This Section
Doug has spoken at every Microsoft FoxPro Developers Conference DevCon since and at user groups and developer conferences all over the world. Among the new and improved features in Microsoft Visual FoxPro 9, you'll find the ability to extend the behavior of the reporting system when running reports. In this article, you'll learn about Visual FoxPro 9's report listener concept, how it receives events as a report runs, and how you can create your own listeners to provide different types of output in addition to print and preview. There are incredible improvements in the Visual FoxPro 9 reporting system.
